I have a 2009 Mazda Cx7.

The transmission pan has no drain plug.

I got a fluid transfer pump.

Got out 2.5 quarts.

Will repeat 2 more times a month apart.

What do you think of the idea ?

They never have drain plugs, because you really need to change the filter at the same time.

They don't have drain plugs so you HAVE to take car to mechanic or dealer.

No transmission fluid is indestructible.

Because changing transmission fluid is a rarity. You should get a new gasket, filter, and do what they recommend which is to drop the pan and lower one corner first to catch the overflow before you lower it entirely to get the remainder. Changing it in a span of a few months is really not the norm.

I've never seen a transmission WITH a drain plug. What are you saying? You're sucking the fluid out of the filler hose? Why? I'll grant they may have been jerks and made it so that there's a frame spar across the pan so you can't get it off or something. Not googling for the procedure, but to me it's what I said earlier. Undo all but one of the 16/18/20 fasteners and tilt the pan down to catch what's over the pan top. Then lower it more to get more out until you can release that last bolt and drop the entire pan. Clean the pan, put on a new gasket (try rockauto.com) for stuff like that, I like that site. And get a new filter since you have the pan down. Also recommend you do have a torque wrench and find the correct torque for the bolts. That and the head gasket are about the only two car items which I take the time to torque properly.

SOLVED

Yes I sucked it out the dipstick.

I will still have my mechanic drop the pan and change the filter.

I will be curious as to how much the pan holds ?

The filter may have prevented the hose from reaching the bottom of the pan.

The filter on rockauto looks more like a mesh screen than a filter.

Fluid capacities are generally listed in the owners manual or available online.

It's not in my owner's manual nor could I find it online.

No biggie.

You do realize there are car forums, and even Mazda forums, I suppose. I'm not sure I understand posting these sorts of questions in a Linux forum. But whatever...

Why does it bother you ?

This is a General forum where any subject is good.

Of course and I have posted at Mazda forums and at rec.autos.tech as well.

But after more than 6 decades, I have learned that a part of wisdom is always seeking other folks knowledge.

This forum has many more participants than selective forums.

So the chance that someone has my make of car is possible. :-)

Mine has a drain plug.

What kind of car ?

It doesn't bother me, it just seems strange. I wouldn't post a question about Linux in a car forum, either. But you're certainly free to post whatever you like.

A car forum probably would not have a general forum either.

Do you look on some of the Google groups ?

It's amazing the plethora of topics that get posted.
